EDV/ARD B. NOWOSIELSKI, OF BLOMFIELD, NEWT JERSEY, ASSIGNOR T0 SPLTDOR'E" ELECTRICAL COMPANY, 0F NEWARK, NEW JERSEY,

enviame-Posa? ron ELECTRIC CABLES.

Application ile November 29, 1918.

lle it known that l, Enwxiu) l. Nowosiiiiisur. a citizen ot' the United States, residing at lilooin'tield, in the count)v ot' Essex and State ot' New Jersey, have invented certain new and useful Improvements in Bindingi Posts for Electric Cables, o twhieh the following is a specification.

My invention relates to binding` posts for Specification of Letters Fatcnt.

horse )ower ot' the engine used and considerably more care must be used in attaching the electric cables to the ignition generator than on an automobile or boat.

The object ot iny invention is to provide a binding post which will give a strong, reliable connection, both electrically and mechanically, and one which will be practically water and dust prooi.

Other and further objects will he apparent from a study of' the specification taken in connection with the drawing which forms a part thereof.

n the drawing, Figure l illustrates a sectional view of one type of terminal bloeit with the cable removed.

Fig. i), is a part sectional View of the device shown in Fig. l but with the cable in place.

l'n the drawing, l illustrates a block of insulating material having two bores 2 and 3 which, in the-torni ot' device shown, are substantially at right angles to each othe' Seated within the bore 2 is a inetallic'ronnecting piece t which has a threaded hole ci.' opening iii line with the. boring 2. Seated iii the bottom ot the threaded hole is a resilient member 5 preferably in the form of a spiral spring. ln the outer end ot the threaded hole is a screw (i. ln line with the bore 3 is an opening 'l' in the metallic connecting piece l. ril`hc spring 5 extends over the open ing 7 so that a cable. 8, preferably having a series of stranded conductors t), from which the insulation has been removed, is adapted.

Serial No. 264,527.

to be inserted into the boring 3 in such a manner that the bai-ed ends 9 of the electric conductors will pass between. the convolutions ot' the spring 5 where they are securely gripped by the said convolntions on the ting up ot the screw as shown in Fig. 2.' ln the. application oi my invention to type ot terminal block shown, the boring 2 extends all the. way through the block and the metallic connecting piece -l is preferably an integral structure niolded i within the block. As snown, one end ot' the metallic piece Jfis bored out at 10 to receive a contact brush adapted to make contact with any suitable part from which it is desired to col-- lect electric current.

I do not wish to be limited to the partic- 'ular type of terminal block shown as niy invention may be applied to various types of distributor blocks; for example, an eight cylinder block ot the type shown and described in the patent application ot ldivard J. Tomlinson, Serial No. 2,1?,8322 tiled February 1S, 1918. lVlien in v invention is applied to a block of this character the end 11 of the metallic connecting` piece is preferably iiush with the surface of the insulation so that a. distributing finger within the block and carrying a distributing brush may come in contact or in a position of contact, provided a Jump spark is used, with the metallic connecting piece. lt is therefore apparent that the torni of the metallic connecting piece t may be varied to suit the rerpiired conditions.

llt will also be apparent that other changes' niay. be inade in the details without departing troni the spirit oi inyl invention and the scope ot the appended claims.

Having thus described iny iiw'cntion ,vnat l claim is l. In a device ot the character described, the combination ot a block et insulating ina teiial havili'g two borings, a metallic connecting piece'sccureliv held in said insulation and having a threaded opening in line 'with one ot' said borings, a coiled spring carijied in the bottoni ot' said threaded opening" a-uda screw at t-hc outer end thereof, said coiled spring adapted to receive and grip th'l barcd conductor ends ot an electric cable introduced into the other of said borings when said screw is turned against the coiled spring.

2. In a device of the cha 'acter described,

the combination of a block of insnlaing inaleiial having two bolings, a metallic cennecting piece secuifelliy held in saidl insulation and leaving an opening in line with one of seid beiings and an opening inte the ethei' ef said bei'inpgs, a celled resilient inem bei` sealed in lie bottoni el the metallic cennec piece eifel. the opening leading te the second n'ieiil'iened boring, means carried by l'ie ineellie connecting piece in the lii's'i. mentioned boring fev; compressing the coiled i'eeilien means te cause it le seize and held t .e bare ends of conductors of an.` electric cable zicleptedte he inseited'in the second mentioned bering.

S.' ln a. device of the character described) l-he ceinbinatienef a bleek of insulating ina- 'texial havingtivo boi'ings sulgisiantially ab right angles te each other, a metallic con'- necting piece securelyY held in said insideien and having` a threaded hole extending entwardly in line with ene ell said berings and an' opening znljaeenl. the bottoni el the hieaded hele leading inte the seeeinl boi'- ing. resilient means seated in lie betteln el said lvhiv'eaded hele and h-iving a numbeil of its cenvelutions extending evei the (mening the second bulking3 a stranded leadii' ie cable adapted lie have its eared ends in the second boring and enl'ei' between the cenvoluliens 0l said resilient ineinbei' whereby when said e yew set up 1n the metallic cei'ineeting piece lhe cable ends aire gripped between the eonveliiitionsY ef seid resilient member.

el. ln a device el: the class described, the eeinbinatien of a hlecl; ef insulaing malei'ial having e metallic eenlact piece held ihei'ein/` a spring; and screw eai'iied by said Contact piece and en Opening into the block and Contact piece adapted lie ieceii'e an electric cable in such a manner that the bei'ed ends ef the cable cendueei: may pass between he cenveluliiens el' said spring for the pinpese ef being;- Securely clamped thereby when the screw is sciened up against Jdie sprinq.,

ln a device of the class deeciibed, the combination of a bleek el' insulating material having` i inet-allie Contact piece extending substantially theretlnfengh, a spring and screw carried in one part el the Contact piece Ywhile the other part is adapted te receive a brush, an opening inte the bleek and contact piece adapl'ed te receive an electrie cable in sneh a n'xannei` that the baied ends el' the Cable eendncoi' may pass between the cenvolutiens 01E said spring 'for the pun pese el' beingI securelyv elaznped thereby Awhen vthe Screw screwed up against the spi'ii'ig.
